PwC Manager interview questions

First interview was conducted well (1-1) and I recieved strong feedback. Had second interview (inc. case study) and recieved no response or follow-up communication after 6 business days. I sent a brief and polite message to the PwC recruiter I had been liaising with well up until this point, asking if they could please advise when I would be due an update on the position I had interviewed for. I recieved no response and was 'ghosted', to coin the popular phrase. No call and not even a basic rejection template email sent in return. I've heard of this happening with some companies but was shocked when this unprofessional behaviour occurred during my job application process with the PwC UK Deals team. Eventually I noticed that my applicant status had changed and I found out that I was unsuccessful after checking the application status on the off-chance one day (not even an automated email notification recieved). I'm definitely not sour about being unsuccessful (you can't win them all!), but it was the treatment recieved as an applicant which was disappointing, given that substantial time was put into interview preparation. The experience has somewhat changed what was previously a high opinion of PwC, which is unfortunate.

Good questions, not so difficult. Some tricky questions but ok can be managed. Three rounds of interviews. One with same job role, second with next job role third one with engagement manager usually the onshore team
